The best salespeople read constantly. Books, newspapers, newsletters, online courses… and blogs. We live in an age where there is an enormous amount of great information available for free about business, marketing, advertising, and sales.

Here is some required smartphone reading for anyone who works in media sales or advertising:

 Great Advertising, Marketing and Sales Blogs

1. Dan O’Day Talks about Radio  — The ostensible subject is radio, but about 50% of the time he is talking about advertising, and what he says can apply to television, Internet, and other media just as well as radio. His Commercial Smackdowns, in which he gleefully dismantles a radio ad, are both instructive and a great deal of fun.
2. Jeffrey Gitomer’s Sales Caffeine — not technically a blog (he has one of those, too but rarely posts). You have to subscribe by email to get this. Gitomer, the author of dozens of sales books including Little Red Book of Selling: 12.5 Principles of Sales Greatness, has been sending out these emails since 2001. He has been known to repeat himself, which is not surprising when you think about having to write 52 of these a year for 15 years. But he lives and breathes sales, has strong opinions, and knows what the heck he’s talking about.
3. The Jim Doyle & Associates Blog: In the interest of full disclosure, let me point out that my day job is as a consultant and sales trainer for Jim Doyle & Associates. But I was a paying customer of this company before they hired me – when I was a radio account executive, I paid out of my pocket to be part of Jim’s sales coaching program. Jim himself wrote Don’t Just Make A Sale… Make A Difference: How Top Achievers Approach Advertising Sales. He, Tom Ray, Pat Norris and John Hannon all provide content to the blog. If you sell radio, television, print, online, billboards, or any other media, this stuff works. 
4. Monday Morning Memo Every Monday, Roy Williams (the Wizard of Ads, not the basketball coach) pontificates about advertising, marketing, persuasion, and anything else that he wants the world to know. Sometimes, he wants the world to know how smart he is, so his blog does occasionally go off in the weeds. But more often than not, he has excellent advice on how to enter somebody’s mind and convince them to do or think something. His book Secret Formulas of the Wizard of Ads: Turning Paupers into Princes and Lead into Gold  is required reading for anyone who works in advertising, or wants to.
5. Sam Richter’s Know More Blog  Richter is the author of Take the Cold Out of Cold Calling, a terrific book on how to research prospects online. He offers a variety resources, some for free and some for money. He is a blog tackles a variety of topics, from sales techniques to to search for information to the value of social media.
